Answer:
<em>The correct option is C) chlorine</em>
Explanation:
Sea water contains salts in abundance. It can be described as the water which makes up the oceans and the seas. It is known to contain approximately 96.5% water and 2,5 percent of salts. Sodium and chloride ions are the most abundant salt ions to be found in the sea. The concentration of chloride ions is 0.546 mol/kg and the concentration of sodium ions is 0.469 mol/kg. Hence, chloride ions are slightly abundant than sodium ions.

Answer:
Negatively charged phosphate groups of two strands are aligned distantly from each other in a DNA double helix.
Explanation:
DNA double helix is formed when the complementary bases of two single DNA strands pair with each other. The formation of double-stranded structures places the negatively charged phosphate groups of two single DNA strands away from each other. This is because complementary base pairs are present between the sugar-phosphate backbones of two DNA strands of a double helix. The double-helical structure also concentrates the nitrogenous bases away from the surrounding watery medium. Altogether, these factors stabilize DNA dyad.
